Patent DE-3374846-D1 (DE)
Title: Automated feed for a punch press and method of using same
Inventor: RUSSON DARREL LEVAN
IPC: B21D43/02
Filed: 1983-05-16
Granted: 1988-01-21
Abstract: The device includes an adjustable height table for receiving a stack of strips of feed stock. The strips are positioned on the table by arms which align the stack to the centerline of punching dies in a punch press. A pneumatic actuated head uses vacuum cups to raise the end of the top strip and insert it into in-feed rolls. The drive for the in-feed rolls also drives an encoder which signals roll movement as the rolls incrementally feed the stock into the punch press. The drive for the feed stock switches to the out-feed rolls once the blanked out stock reaches those rolls, and when the end of the strip passes through the punch press, a control unit is signaled and a new strip is fed into the system. A control unit comprises a control panel, a computer and an interface. Operator commands inputed through the control panel are passed through the interface directly to the computer which in turn sends signals to the approp. parts of the machine.
